What It Means

The command output lists the components installed in an M20 router chassis, including the category or class, component name, operational status, and temperature or speed measurement. Use this command to get a quick status of each component installed in the router chassis. You can also use the show chassis component-name CLI command to get more detailed status information on certain components for isolating problems. For an example, see Display Detailed Component Environmental Information.
